DKTM-016 - My widowed sister-in-law's secret invitation after 5 years

I visited my sister-in-law's place in Seoul during winter break. It's been 5 years since my brother passed away, and she's still living alone, staying chaste. Seeing how beautiful she still is, I asked why she hasn't remarried. She gave me a mysterious smile and said, 'Anyway, since you're here, why don't you stay the night?'
